Description

  The present invention relates to an angle adjustment seat, and more particularly, to an angle adjustment seat that eliminates the shortage of light rays by adjusting the angle of an LED fluorescent lamp.

The prior art will be described below with reference to the drawings. Refer to FIG. FIG. 14 is a perspective view showing a conventional LED fluorescent lamp and a lamp seat. It is a perspective view shown. As shown in FIG. 14, the LED fluorescent lamp 12 is disposed on the socket 11 of the lamp seat 10. The LED fluorescent lamp 12 is fixed and cannot be swung to adjust the angle. Since the LED light arranged in the LED fluorescent lamp 12 emits light linearly and is not irradiated radially, a good light source cannot be obtained unless it is directly under the LED light. In short, it had the disadvantage of insufficient illuminance.

  Since the LED is a point light source and has high directivity, the irradiation area is narrow, unlike a conventional light source. Since the luminous intensity decreases as the distance increases, it has been used relatively well in lighting fixtures that illuminate a short range over a short distance, such as a desk stand.

  In order to solve the disadvantage that the angle of the LED fluorescent lamp 12 cannot be adjusted, a structure capable of adjusting the angle has been devised.

Japanese Patent No. 4872025

The first object of the present invention is to provide an angle adjusting seat that solves the problem that the illumination angle is narrow and the illumination range is limited due to the directivity in the LED lighting apparatus.

To achieve the above object, the present invention provides an angle adjustment seat. The angle adjusting seat of the present invention has a main structure including a side surface portion, a rotating body inner portion, and a rotating body outer portion. The outer side of the rotating body has a plurality of integrally formed coupling protrusions, a plurality of insertions, two perforations, a fitting groove piece side, and a coupling seat that is symmetrical in cross section at the rear. The inner side of the rotating body has a plurality of integrally formed insertion holes, coupling holes, a fitting groove piece side having a range of 180 degrees, and a coupling seat that is symmetrical in the cross section of the rear part. The side surface portion is provided with a through hole in the upper portion and a seat in the lower portion. The present invention further includes a positioning body, a fitting body, and a positioning knob. The positioning knob has a plurality of positioning grooves on the bottom surface of the knob. The knob is integrally formed so that the rotating rod extends downward. A stopper is integrally formed at the end. The positioning body includes a left block and a right block. The left block is provided with two recesses. The right block has fitting protrusions on both sides and a positioning protrusion on the top. The left block and the right block are combined by a recess and a protrusion, and are fitted onto the rotating rod of the positioning knob. The fitting body is provided with fitting protrusions on both sides.

  Since the angle adjusting seat of the present invention swings for adjusting the angle of the LED fluorescent lamp, it is possible to solve the shortage of the light amount due to the defective illumination angle. At the same time, convenience in use can be improved.
